Study and Analysis of an Ankle Joint to Design a Pedorthosis for Children with Cavus Clubfoot Deformity

Abstract

Most of the vertebrates have foot which is an anatomical structure and also newlinethe terminal portion for the limb that assists in locomotion and acts as a weight bearing newlinestructure. The human foot is one of the complex anatomical structure with 26 bones, newline33 joints and over hundred muscles, tendons and ligaments. Any deformity in the foot newlineaffects the posture and walking pattern of the subject. newlineThe Finite Element Modelling (FEM) is one of the tool used for newlineinvestigating the biomechanical behaviour of foot under different conditions. As newlinereported in the existing literatures, several finite element foot models are developed by newlineimposing simplifications on its anatomy by considering the ligaments as tension free newlinelink elements and material properties. The results of the simulation studies on these newlinefinite element models has a significant variance compared to the experimental results newline
